Why Is Normal Probability Distribution Important

Normal distribution is also known as gaussian distribution. This is due to the fact that they.

Other parametric and nonparametric statistical models also play an important role in medicine and the health sciences.

Why is normal probability distribution important. Importance of normal distribution. Central theorem means relationship between shape of population distribution and shape of sampling distribution of mean. Since probability theory is very much helpful for making predictions and decisions it plays a vital role in statistical research investigations.

Gaussiannormal distribution gaussiannormal distribution is a continuous probability distribution function where random variable lies symmetrically around a mean m and variance s2. It is often desirable to use the normal distribution in place of another probability distribution. Today statistics and the normal distribution have a place in almost every scientific endeavor.

Remember though that the binomial distribution is discrete whereas the normal distribution is continuous. These are the properties of normal distribution. The probability distribution of a binomial random variable is called the binomial distribution.

Normal distribution represents the behavior of most of the situations in the universe that is why its called a normal distribution. In particular it is convenient to replace the binomial distribution with the normal when certain conditions are met. Lastly an important point to note is that simple predictive models are usually the most used models.

Their importance is partly due to the central limit theorem. This means that sampling distribution of mean approaches normal as sample size increase. Normal distribution also known as the gaussian distribution is a probability distribution that is symmetric about the mean showing that data near the mean are more frequent in occurrence than.

Although the normal distribution provides a good probability model for many phenomena in the real world it does not apply universally. These trials are independent and the outcome of one trial does not affect the outcome of another trial. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real valued random variables whose distributions are not known.

1 it has one of the important properties called central theorem.
